Cannot read property 'length' of undefined Node JS Server
Following a tutorial online to incorporate mysql into node js, and I am receiving an error on code line 12. Wondering what went wrong. (server.js file)
10| <div class="=">
11| <div class="col s12">

13| <table class="table">

Looks like the "items" object doesn't exist. Change line 12 to be: <% if (items && items.length > 0) { %>} -Why- it doesn't exist is difficult to explain without more code (it could potentially be a whole range of things)

This means there was no value of variable items passed to template render so it was undefined

Because of items variable is undefined. whenever you try to find a length of an undefined variable you will see this type of error. Please, console.log/print the items there should be an issue with that only.
